And yes, to start detonation of the ocean you need very large fuse -
not ordinary fission bomb as in case of Tellers tube, but a very
powerful hydrogen bomb. For example, to start detonation of 1 to 300
deiterium you need explosion with power of 10**7 megatons (as 1979
artile states) - so the wight of the fuse would be around million
tons.
Of course, it would be very difficult to reate such large bomb in near
future (but not impossible) in case of use of nanomanyfacturing in
space.
But someone could use two stage detonation of the plenet -
1. to find (or create) a small (100 meters in diameter) place with
very high concentration of deiterium inside the planet - like deposit
of mineral on Earth. The 1979 article said that: ".... If thereby
highly enriched in deuterium (10 at. %), thermonuclear detonation of
such layers could be initiated artificially with attainable nuclear
explosives". So 10 per cent concentration would be enogh.
And detonate it this use of common thermonuclear bomb - may be of
several gygatons power.
2. The explosion of this small deposite will give needed 10 **7
megatons which are enogh to fuse detonation wave in large but less
enriched surroundings.
